EKO_Q18_AGW Version 7.1.1

PHOTO REQUIRED of above grade wall insulation per ANSI/RESNET/ICC 301-2019 APPENDIX B and MINHERS Chapter 9. Raters/RFIs are responsible for documenting reasons for missing photos. For above grade walls, confirm that the wall types, insulation types, insulation materials, insulation thicknesses, insulation grades, R-values, stud types, stud spacings/dimensions, framing factors, surface areas, surface colors and locations which are entered into the software correspond with plans and/or field data collected by the Rater/RFI for the actual condition of the rated home. For rim and band joists, confirm that the types, R-values, surface areas and locations which are entered into the software correspond with plans and/or field data collected by the Rater/RFI for the actual condition of the rated home.

• Be sure that where multiple above grade wall types exist or where multiple rim/band joists types exist they are handled separately, including where their “location” with respect to conditioned areas of the home may vary between wall/rim and band types and within the same wall/rim and band type.

SCORING:

• Satisfactory: No errors in modeling
• 1: one to two minor errors in modeling (listed below) (this is per modeled wall)
• 2: NO PHOTO OR three to four minor errors (listed below) in modeling OR one to two major errors in modeling (this is per modeled wall)
• 3: five or more minor errors (listed below) OR three or more major errors in modeling (listed below) (this is per modeled

GUIDANCE:

Minor AGW Modeling Errors:

• Incorrect Wall Construction modeled
• Insulation R-Value of each modeled AGW off by 5% to 10%
• Insulation thickness of each modeled AGW off by 0.5 to <1.0 inch
• Incorrect Gypsum thickness modeled
• AGW Surface Area of each modeled AGW off by 4% to 7%
• Incorrect Surface Color modeled
• Incorrect Insulation Location modeled

Major AGW Modeling Errors:

• Insulation R-Value of each modeled AGW off by greater than 10%
• Insulation thickness of each modeled AGW off by greater than 1.0 inch
• Incorrect Insulation Grade value modeled (based on ANSI/RESNET/ICC 301-2019 Appendix A - depth/void variance for insulation type and grade)
• Incorrect stud depth, spacing, or framing fraction modeled
• AGW Surface Area of each modeled AGW off by greater than 7%
